SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Canary Watch prevents bad releases from silently degrading a site by continuously checking real user signals and key behaviors after deployment.

Core Features & Use Cases

  • Post-deploy regression monitoring: Detects HTTP failures, new console errors, network/API issues, and performance regressions against a baseline.
  • Launch-window validation: Supports quick checks, sustained watching, and staging-vs-production diff comparisons for risky changes.
  • Actionable alerting and reporting: Emits structured canary reports and flags critical, warning, and info events, optionally notifying via webhook.

Quick Start

Run canary-watch against your deployed URL to confirm critical health checks stay within thresholds before you declare the release successful.

FAQPage Schema
How do I monitor post-deploy regressions for HTTP availability and console errors?

Post-deploy regression monitoring checks a deployed URL for HTTP failures, new console errors, network/API health, and performance metrics against a baseline. Canary Watch applies looped health checks with baseline-aware threshold evaluation to detect these regressions after deployment.

What is canary monitoring and how does it validate a launch window?

Canary monitoring validates a launch window by continuously checking real user signals and key behaviors after deployment. Canary Watch supports quick checks, sustained watching, and staging-vs-production diff comparisons to ensure critical health checks stay within thresholds before declaring a release successful.

Can I use staging vs production diff comparisons to verify risky dependency upgrades?

Yes, staging vs production diff comparisons verify risky dependency upgrades by comparing health metrics across both environments. Canary Watch applies baseline-aware checks throughout the launch window, detecting client-side errors and performance regressions before promoting to production.

How do I set up structured reporting and escalation rules for critical web service events?

Structured reporting and escalation rules for critical web service events emit canary reports flagging critical, warning, and info events. Canary Watch applies escalation rules for critical versus warning events and optionally notifies via webhook during post-deploy health checks.

Does canary monitoring work with RBAC-aware web services for post-deploy verification?

Canary monitoring works with RBAC-aware web services by applying looped health checks that verify HTTP availability, client-side errors, and critical content after deployment. Canary Watch evaluates these signals against baseline thresholds during production or staging deploys.

When should I not use baseline-aware health checks for post-deploy verification?

Baseline-aware health checks for post-deploy verification are less effective without an established baseline to compare against. Canary Watch requires baseline-aware threshold evaluation to detect performance regressions and API health issues, meaning first-time deployments without prior metrics may lack comparative context.
